VESSELS
Versatile fleet of specialised, multipurpose offshore vessels
N-Sea operates a fleet of 14 specialised, multipurpose offshore vessels equipped with state-of-the-art subsea systems and equipment. Our vessels are ideally suited to support a wide range of smart subsea solutions across all phases of the offshore asset life cycle, from development and installation through to operation and decommissioning.
Across our fleet, highly experienced and dedicated teams operate worldwide, consistently delivering offshore operations to the highest standards of excellence.
Cable Lay Vessels (CLV)
Subsea cable repair and installation operations, DP2 capability, knuckle boom AHC cranes, and large deck space
Dive Support Vessels (DSV)
Subsea IRM and construction operations, DP3, knuckle boom AHC crane, and large deck space
Survey Vessels
Geophysical and geotechnical survey, inspection and subsea construction operations, DP2
Offshore Support Vessels (OSV)
Wide range of subsea support operations, from survey and UXO to IRM, with DP2 capability and large deck space
Nearshore Survey Vessels
Fast survey operations and crew transport
EQUIPMENT
State-of-the-art subsea systems and equipment
Our primary operations support base for all offshore operations in Europe is in IJmuiden, the Netherlands. This strategically positioned support base, close Amsterdam and Schiphol Airport, provides direct access to the North Sea.
The unique location and organisational set-up allow us to efficiently manage our asset base and support our fleet and projects from a single location. The base is situated close to the quayside, enabling efficient mobilisation and demobilisation of vessels and equipment. Standardised working methods, the use of digitised track & trace systems, and support from a dedicated team of in-house technicians and experts allow us to minimise operational downtime across our projects.
Modular Cable Installation Equipment
Three in-house designed modular cable installation systems, developed with a strong focus on maintaining cable integrity and providing the flexibility to handle various types of cables and joints.
Remotely Operated Vehicles (ROVs)
Twelve highly manoeuvrable underwater vehicles used for cable, umbilical and pipeline localisation, post-lay seabed cover surveys, UXO localisation, seabed clearance operations, inspection, repair and maintenance (IRM) of subsea structures, and diver support and observation.
MagSense Wing Systems
Six MagSense systems designed to detect subsea magnetic anomalies, such as unexploded ordnance (UXO).
Scanfish Systems
Four remotely operated towed Scanfish systems to support survey operations
CPT Tool
Cone Penetration Test (CPT) geotechnical tool to measure seabed soils.
AUX ROVs
Two AUX ROVs, ideally suited for boulder clearance.
COBRA Mine Disposal System
A non-electric firing system with a wireless ignition for the neutralisation or disposal of explosive ordnance.
Launch and Recovery Systems (LARS)
Fourteen Launch and Recovery Systems (LARS) used to safely deploy and retrieve divers, subsea tools, vehicles, craft and equipment to and from the water making LARS an essential component for offshore launch and recovery operations.
Air Diving Systems
Three fully IMCA-compliant air diving systems used to safely manage subsea air-diving operations for IRM works on various subsea structures, including platform jackets.
