Following 3 years of successful operations, N-Sea - the Inspection, Maintenance and Repair (IMR) specialist - has extended its charter agreement with Siem Offshore, concerning its offshore subsea construction vessel, Siem N-Sea, previously Siem Stork. The agreement has a duration of up to 6 years, having begun on January 1, 2015.

The Siem N-Sea is a dive, multi-support and construction vessel, designed to meet the needs of the offshore subsea industry. It is one amongst N-Sea's fleet of six dive support and specialist intervention vessels, designed to deliver a range of subsea services for offshore assets, platforms, FPSOs and renewables operations, with minimal impact made upon production.

N-Sea strives to provide customers with safe, sound and swift remedies, and the ship is equipped with exceptionally efficient azimuth thrusters and a DPII dynamic positioning system for safe and economic operations on a world wide scale. Featuring N-Sea's ground-breaking TUP Diving System®, the vessel is also fitted with complete air and nitrox diving spread and daughter craft, WROV and Obs ROV.

A high focus on reduced fuel consumption through diesel electric propulsion is in keeping with N-Sea's commitment to an improved environmental performance across its fleet.

Commenting on the agreement extension, N-Sea CEO, Gerard Keser said: "N-Sea is extremely pleased to have extended its original agreement with Siem Offshore. It is clear testament to proven capability of both the vessel and the N-Sea team aboard the Siem N-Sea and back onshore. We look forward to the continuation of this excellent working relationship."

N-Sea is known for its innovative work as an independent offshore subsea contractor, specialising in IMR services for the international oil and gas, renewable and telecom/utility industries, as well as for civil contracting communities. With particular focus on North Sea activity, N-Sea provides offshore and survey services to major operators and service companies alike.
