A career in Marine Engineering spans complex environments: from delivering high-spec naval vessels and offshore assets, to managing multi-million dollar dry dock turnarounds and mooring analyses for global shipping corporations.

Nikhil Chutturu, our next pathbreaker, Naval Architect at Turnagain (Florida), is involved in the analysis, design, and verification of mooring systems for large vessels, particularly cruise ships.

Nikhil talks to Shyam Krishnamurthy from The Interview Portal about maritime careers that require a strong foundation in hydrodynamics, structural mechanics, and applied engineering mathematics, along with practical knowledge of international shipping standards and guidelines.

For students, this is a career that constantly challenges you, enhances your understanding and exposes you to real-world constraints.

Nikhil, Your Background ?

I was born and brought up in the coastal city of Visakhapatnam, Andhra Pradesh in a middle-class family that emphasized education, discipline, and self-reliance. Although my parents were not from engineering backgrounds, they strongly believed in discipline and structured education. From an early age, my favorite pastime was to watch the cargo ships enter and exit the channel for loading/ unloading at visakhapatnam port. Academically, I gravitated toward mathematics and physics, but what truly interested me was applied engineering, where theory transforms into tangible outcomes. These early interests gradually shaped my inclination toward engineering fields that combine analytical study with real-world impact. Exposure to coastal environments, ports, and maritime activity during my formative years planted the foundation for my eventual career in naval architecture and marine engineering.

What did you do for graduation/ post graduation ?

I completed my Bachelor’s degree in Naval Architecture & Marine Engineering from Andhra University, where I studied ship design, hydrostatics, hydrodynamics, marine structures, and offshore engineering fundamentals. The program provided a strong foundation for both floating structures and marine systems. Although I do not yet hold a formal postgraduate degree, I have consistently pursued advanced self-driven learning through professional practice, industry standards, engineering software, and independent research. I am actively exploring PhD opportunities in marine hydrodynamics and coastal or offshore engineering to further formalize my research interests.

What were some of the key influences that led you to such an offbeat, unconventional, and unique career in Marine Engineering?

The scale, complexity, and responsibility associated with marine and offshore structures strongly appealed to me. Ships and offshore systems operate in extreme environments and must perform safely under uncertainty, a challenge that I found intellectually and professionally fulfilling.

Family members working in the merchant navy were a big influence on me to pursue a naval architecture degree. Employment opportunities were also varied and rich in a niche field like Naval Architecture.

After joining the undergrad course, alumni visits were frequent which helped us understand the different career paths that are available after the course. Their experiences entailed working at PSU Shipyards, design consultancies, classification societies and Indian Navy.

Although, I was able to secure a seat in one of the NITs, I chose to proceed with Andhra University (Naval Architecture) due to its presence in Vizag (my hometown) and multiple opportunities within the city (Hindustan Shipyard, NSTL, ship design companies).

How did you plan the steps to get into the career you wanted? Or how did you make a transition to a new career? Tell us about your career path

My approach has been to build depth first and then breadth—mastering engineering fundamentals before expanding into adjacent domains such as mooring analysis, dry docking, hydrodynamics, and project planning. My objective was to not get too comfortable in any one single role, as you will see below. I have constantly broken myself out of my comfort zone, thereby expanding my footprint in multiple domains within the maritime sector, giving me a niche set of skills ranging from rigorous technical study involving hydrodynamics to dry docking project management for some of the largest cruise ships in the world. I’ve constantly pushed my geographic footprint all the way from my hometown Vizag, India to the USA, Spain, France, Japan and Singapore.

I began my career in offshore engineering as Graduate Engineer Trainee (GET) and then became Senior Engineer at L&T Hydrocarbon Engineering Ltd, Mumbai, India , performing naval and structural analyses for the transportation and installation of offshore jackets and topsides. Offshore jackets are fixed platforms installed on the seabed of the offshore oil field. They are trussed structures designed to withstand wind, wave and current loads. The jackets serve many purposes such as drilling, processing and accommodation. I specialise in transportation of these jackets and topside (if jackets are legs, topsides are the body) to the offshore location and methodically installing them using floating cranes and barges. I do time domain simulations to understand the dynamic load impacts on structure, slings and stability of the operation.

This role instilled strong analytical discipline and familiarity with international design standards. This job was my foundation for my continued interest in the field of hydrodynamics and formed a backbone for my current role as mooring engineer. L&T was my first exposure to large corporate MNC culture, dealing with multiple projects for clients such as ONGC, HPCL, Saudi Aramco and ADNOC.

My next role was Assistant Manager (Engineering) at Hindustan Shipyard Ltd, Vizag, India

To gain hands-on exposure, I transitioned into shipbuilding, contributing to the construction of tugs, diving support vessels, and a floating dock for the Indian Navy. This phase solidified my understanding of fabrication, construct-ability, and system integration. Working at HSL also helped me to realistically relate the design drawings to actual construction with deadlines and quality control in mind. I was fortunate to be involved with state of the art diving support ships construction, which were indigenously built for the first time in any yard in India.

Diving support ships are a unique class of vessels that are built to conduct deep sea operations (ranging from 50m to 300m). In the commercial world, these ships facilitate professional divers to conduct seabed inspections, repair works mainly in the subsea pipelines and asset management. Divers do not use normal air mixture containing (N2, O2 and trace), instead to sustain such depths, their breathing air is made of Heliox mixture (Helium% + oxygen%), which enables them to conditionally stay and work longer and safer at such depths. These vessels are to be specifically built to keep the sensitive apparatus running smoothly with layers of redundancy. For the navy, these vessels shall be used for deep sea submarine rescue operations, in case of an incident. I was the project officer in charge for construction of the diving compartments in the ship, along with testing and trials of the diving equipment from the external vendors.

I then moved to the United States Technology Associates Inc, New Orleans, USA where I worked as Naval Architect II. I worked on ship design and analysis projects involving U.S. government agencies such as the U.S. Army Corps of Engineers and NOAA, gaining exposure to regulatory-driven engineering and public infrastructure projects. Although this role was brief, I grabbed the opportunities that were ripe in the US market, which were fruitful both financially and professionally.

My stint at TAI was very small, but within that I was able to get hands-on design calculations for structural dept for the NOAA class B research vessel. Another project that I was instrumental in delivery was USACE conducting lightship analysis and getting final approval documents from classification society.

My next stint was at Carnival Cruise Line, Miami, USA where I was involved in Dry Dock Project Management as Planning Engineer. Ships stay in water from the moment they are launched till the end of their life. During this period they attract lot of biofouling (algae, mussels, barnacles, etc), constantly degrade (corrosion, choking of overboard valves) and need underwater maintenance (propeller repair, fin stabilizer, bow thrusters maintenance, etc). To do this we take the ship into a dock, lock the gate, pump the water out and position the ship on blocks. This process is called dry docking. This operation may sound easy but in reality is a daunting task for an experienced professional. Technical challenges include narrow tide window, stability of vessels, improper ballasting can lead to toppling of vessels in the dock leading to loss of life and property. Commercial challenges include cost of men and material, logistical coordination, stringent life and safety requirements, rent of the dock services. Dry docking is almost a CAPEX investment into a depreciating asset, the frequency of this operation is governed by classification society requirements (DNV, ABS, Lloyds, ABS, etc). I was co-managing such dry dock operations for Carnival Cruise line fleet of ships along with a Senior Manager. The cost of each dry docking is at least 12 million USD.

At Carnival Corporation, I co-managed dry dock planning and execution for large cruise ships, overseeing schedules, budgets, risk assessments, stakeholder coordination, and on-site inspections.

This role heavily banked on my previous shipyard experience, helping me get an edge. The role involved technical inspections, budgetary control and timely completion of dry docks for large cruise ships at various global shipyards including Navantia (Spain), Chantier Naval de Marseille (France), Admiralty Yard (Singapore) and Tuas Boulevard Yard (Singapore). In addition to this, this job required me to travel extensively to multiple ports within the US and other foreign nations.

I currently work as a Mooring Engineer at Turnagain Marine Construction, Fort Lauderdale, USA , designing and assessing mooring systems for large cruise ships across Alaska, the Caribbean, and North America. Here I utilize my combined experience working with cruise ships, hydrodynamics and mooring experience to safely design the mooring and port hardware necessary for safe berthing and operations of cruise operations.

How did you get your first break ?

My first professional break came through campus placement at Andhra University. I joined L&T as a GET in July 2017 at Bangalore location. I entered the USA on an H1B visa, through my first company Technology Associates Inc.

What were some of the challenges you faced? How did you address them?

Bridging Theory and Practice:

Addressed by transitioning into shipbuilding and site-based roles. Never get too comfortable as the first 10 years of professional experience is where maximum learning is possible.

International Career Transition:

I overcame challenges by continuous learning, adaptability, and understanding new standards and work cultures. The initial culture shock was there, but staying out of my comfort zone allowed me to embrace a number of experiences, including exploring other countries, languages, and opportunities to work with multiple nationalities.

Balancing Depth and Breadth:

Resolved by anchoring my expertise in mooring and hydrodynamics while remaining conversant across related disciplines. My base is still core naval architecture, I constantly revise them to keep myself relevant, such that any complex problem can be broken into smaller parts and solved in a first principles approach.

Where do you work now?

I currently work as a Mooring Engineer at Turnagain Marine Construction, where I am involved in the analysis, design, and verification of mooring systems for large vessels, particularly cruise ships, operating in diverse and often challenging environmental conditions across North America, Alaska, and the Caribbean.

A mooring is any permanent structure to which a seaborne vessel (such as a boat, ship, or amphibious aircraft) may be secured. Examples include quays, wharfs, jetties, piers, anchor buoys, and mooring buoys. A ship is secured to a mooring to forestall free movement of the ship on the water. Mooring is nothing but securing a floating vessel to a fixed or other floating structure. Primary examples include ships at a port are moored to the jetty/ quay/ pier. The mooring is done through chains, ropes and steel wires of marine grade depending on the location, water depth and duration of mooring required for.

What problems do you solve?

My primary responsibility is to ensure that vessels remain safely and reliably secured to port infrastructure under varying combinations of wind, current, water level, and operational loading. This involves assessing mooring line forces, fender reactions, vessel offsets, and overall system stability to prevent incidents such as line failure, excessive vessel movement, or damage to port assets. The problems I solve often lie at the intersection of physics, safety, and operational practicality, where conservative assumptions must be balanced against real-world constraints.

What skills are needed for the job? How did you acquire them?

This role requires a strong foundation in hydrodynamics, structural mechanics, and applied engineering mathematics, along with practical knowledge of international mooring standards and guidelines. Proficiency in specialized mooring analysis software and the ability to interpret complex load cases are essential. I acquired these skills progressively through formal education, hands-on project experience, mentorship from senior engineers, and extensive self study of industry standards. Additionally, I developed programming and automation skills to streamline calculations and improve the clarity and repeatability of engineering analyses.

What is a typical day like?

A typical day involves a combination of analytical and collaborative work. I may begin by reviewing environmental data or project requirements, followed by running mooring analyses and evaluating results against safety criteria. This is often complemented by design reviews, coordination meetings with clients or port authorities, and internal discussions with multidisciplinary teams. I also spend time refining internal tools, templates, and workflows to improve efficiency and consistency across projects.

What is it that you love about this job?

What I value most about this role is the responsibility it carries. Even relatively small engineering decisions can have significant consequences for safety, operations, and the environment. The work demands both technical rigor and sound judgment, and it is deeply satisfying to know that my analyses directly contribute to the safe movement and berthing of vessels carrying thousands of people.

How does your work benefit society?

The work I do contributes directly to maritime safety, environmental protection, and the resilience of port infrastructure. Well-designed and properly assessed mooring systems reduce the likelihood of vessel breakaways, collisions, and structural damage, all of which can have serious economic and environmental consequences. By helping ensure safe port operations, my work supports global trade, tourism, and coastal communities while minimizing risks to marine ecosystems.

Tell us an example of a specific memorable work you did that is very close to you!

One of the most meaningful aspects of my career has been working on mooring system assessments for large cruise ships operating in environmentally sensitive and meteorologically demanding regions such as Alaska. These projects required careful consideration of extreme weather, limited port infrastructure, and high passenger safety expectations. Knowing that the reliability of these systems directly affects both human safety and environmental protection made the work especially significant and personally rewarding.

Your advice to students based on your experience?

Based on my experience, I would encourage students to focus on building strong fundamentals before relying heavily on software tools. Actively seek challenging assignments that stretch your understanding and expose you to real-world constraints. Whenever possible, complement theoretical learning with hands-on experience, whether through internships, site visits, or fabrication work. Finally, recognize that careers are rarely linear. Curiosity, adaptability, and sustained effort often matter more than early specialization.

Future Plans ?

Looking ahead, I aim to pursue advanced research in marine hydrodynamics and offshore engineering, potentially through a doctoral program. I am interested in publishing both technical research and experience-based papers that bridge theory and practice. In parallel, I plan to continue developing digital engineering tools that improve safety and decision-making in the maritime industry, while also mentoring young engineers as they begin their professional journeys. My long-term goal is to contribute meaningfully to safer, smarter, and more sustainable marine infrastructure worldwide.
