Greek shipowner Evangelos Marinakis’ offshore fleet is growing with extra newbuildings added to his haul, according to a new NOK 800m ($73m) contract signed with Norway’s Kongsberg Maritime.

The tycoon’s Capital Offshore now has up to 10 platform supply vessels and multipurpose supply vessels at Fujian Mawei Shipbuilding in China.

Kongsberg Maritime will supply an extensive range of equipment, including electric propulsion, automation and energy systems for the vessels, it announced today.

The group called the contract for the battery hybrid ships a “significant win”.

Capital Offshore aims to expand in offshore oil and gas operations.

It first ordered four firm 95-metre PSVs in June, with four options. The Kongsberg deal suggests these options have now been declared.

The Marinakis company then followed the order up with another contract for two MPSVs.

The new vessels are intended for the Brazilian market, Kongsberg said.

Capital Offshore general manager Gerry Ventouris said: “We aim to ensure that these vessels are of the highest quality, and partnering with Kongsberg Maritime is a critical step in achieving that goal.

“This cooperation reflects our commitment to excellence as we expand our operations in the offshore sector,” he added.

Kongsberg Maritime president Lisa Edvardsen Haugan said: “This significant investment in a series of 10 new PSVs signals Capital Offshore’s intent to be a major player in future offshore operations.

“We look forward to building on our long and successful relationship with Fujian Mawei Shipbuilding in China on this exciting project.”

Flexible design

Part of the deal is an energy storage system, which provides power for peak shaving.

The ships will be able to run on a single engine or have full flexibility for engine selection, reducing fuel consumption and emissions.

The propulsion system for each vessel will comprise two US 255 azimuth thrusters, a single ULE PM 155 retractable azimuth thruster and two TT2200 tunnel thrusters, all powered by permanent magnet motors.

The PSVs are believed to be costing between $41m and $43m each, with the MPSVs reportedly priced at $69m each.
