Wide-ranging capabilities.

One Decarbonisation Goal.

The Fisk Tech team has a diverse skillset across multiple maritime industries combined to provide benefits to both the planet and your business.

Fisk Tech is a talented team of marine professionals that are based in the Port of Singapore.

We have taken a different viewpoint to our main competitors when looking at hull cleans and general hull maintenance. A typical approach is to look at hull cleaning only through a diving lens. Fisk Tech takes a wholistic approach, using our engineering expertise and understanding of fleet commercials, then exploiting the latest technology to create bespoke and innovative solutions tailored to individual client needs.

Our team has over 50 years of combined experience of subsea maintenance and repair expertise. This experience covers the various perspectives of fleet managers, naval architects, and commercial dive masters.

Varun founded Fisk Tech in 2021 on the cornerstones of technology, innovation and safe operations to deliver better value for customers, employees and society.

He has also been selected for many executive leadership courses from Maersk and INSEAD.

James Bassadone

Commercial Director

James is originally from Gibraltar and joined Fisk Tech in early 2022 as he is a strong supporter of the value proposition and principles on which the company operates.

He has been working in the biofouling/hull maintenance industry for over 35 years and is 3rd generation family member linked to this trade.

Through his extensive career James has worked both on the shipowner’s side with “AP Møller Maersk” based out of Copenhagen, as well as the service provider side with various companies.

He has been involved in research and development projects for the improvement of underwater hull cleaning technologies.

Under his guidance and supervision as CEO for Cleanhull, James’ team were the first hull cleaning company to be allowed to conduct cleanings at the very busy container terminals in Singapore which had never been allowed to be done before due to the strict requirements from the local authorities.

Through his many years working in the industry, James prides himself in the attention to detail and strives to bring a very different service provider experience to Fisk Tech’s many clients.

Being based out of Copenhagen we can bring a very personal relationship with our clients there, and allows us to operate on both time zones effectively.
