Services
Through our knowledge of offshore development and construction worldwide, we use our experience, equipment, and highly-skilled teams to offer a full package of solutions for the design, transport, installation, and maintenance of subsea cables.
Cable Repair and O&M Services
Rapid-response repair frameworks and maintenance solutions to minimize downtime and keep critical assets online.
​
Subsea cables account for up to 80% of offshore project insurance claims. Failures are costly, and downtime can halt energy delivery or data transfer. Kalypso Offshore minimizes this risk by offering robust operations and maintenance (O&M) solutions and rapid-response cable repair services.
Capabilities include:
-
Emergency repairs – fault identification, cable recovery, jointing, replacement, and reburial.
-
Planned maintenance – condition monitoring, inspection surveys, and preventative interventions.
-
Framework agreements – tiered Bronze, Silver, and Gold packages that secure equipment, vessels, and pre-engineered solutions in advance.
-
Modular repair kits – transportable cable-handling equipment that can be mobilized to vessels of opportunity worldwide.
Client benefits:
-
Minimized downtime with guaranteed response times.
-
Cost efficiency through pre-agreed frameworks and retainer models.
-
Proven track record repairing dozens of subsea cables in Europe and the U.S. Northeast.
Subsea Cable Installation Services
End-to-end installation for export, inter-array, interconnector, umbilical, and telecom cables - from design and engineering to procurement, transport, and offshore lay, burial, and protection.​
​
The integrity of any offshore power or communication network begins with precision installation. Kalypso Offshore offers turnkey installation services for export, inter-array, interconnector, and telecom cables. Our approach integrates front-end engineering, seabed analysis, and tailored execution planning to ensure that every cable is laid with accuracy and long-term resilience in mind.
​
Key capabilities include:
-
End-to-end project management – from route engineering and cable transport to offshore installation and testing.
-
Specialized equipment – modular spreads, cable carousels, trenching tools, and ROVs for deployment in shallow to deep waters.
-
Complex interfaces – turbine, substation, and landfall pull-ins managed with precision.
-
Post-installation protection – burial, CPS fitting, and stabilization to prevent free spans and damage.
​​
Client benefits:
-
Turnkey solution from concept to installation.
-
Optimized lifecycle costs through experienced design and build procedures.
-
Compliance with U.S. Jones Act requirements while leveraging international experience.
Offshore Construction & Supporting Services
Seabed clearance, landfall works, crossings, and subsea deployment and installation - enabling smooth project delivery from shore to deepwater.
​
Every offshore cable project requires more than just laying cable. Kalypso Offshore provides the supporting construction services that make installation possible. By mobilizing experienced offshore teams and flexible equipment spreads, we enable developers to overcome site-specific challenges and ensure project readiness.
Typical supporting activities include:
-
Seabed clearance & preparation – boulder picking, debris removal, and grapnel runs.
-
Landfall works – horizontal directional drilling (HDD) support, beach pulls, and civil integration.
-
Crossing design and installation – mattresses, rock placement, or duct systems to protect cables at intersections.
-
Post-lay remedial works – trenching, burial, or rock-dumping to achieve protection standards.
-
Marine coordination – support vessels, walk-to-work systems, and offshore logistics.
​
Client benefits:
-
One-stop-shop for both installation and enabling works.
-
Reduced coordination burden by using a single contractor for multiple scopes.
-
Flexible approach tailored to local site conditions.
Cable Transportation & Storage
Safe, compliant logistics for cable movement and secure storage - including Jones Act compliant transport in U.S. waters.
​
Safe, compliant logistics are the backbone of any subsea cable project. Kalypso Offshore manages transportation and storage of cables and accessories, ensuring integrity from factory to seabed.
​
Services provided:
-
Cable transportation – Jones Act–compliant transport solutions within U.S. waters and international shipping coordination.
-
Onshore & offshore transpooling – moving cables between baskets and carousels with controlled testing.
-
Short- and long-term storage – secure facilities and systems to maintain cable condition until needed.
-
Cable integrity assurance – electrical and mechanical testing during handling and before deployment.
Client benefits:
-
Seamless integration with installation campaigns.
-
Reduced risk of cable damage during storage or transit.
-
Turnkey logistics management freeing clients from operational burden.
Route Design & Cable Burial Risk Assessment
Subsea environments are complex — with varying seabed conditions, human activity, and natural hazards. Kalypso Offshore’s engineering team provides route design and cable burial risk assessments that optimize safety, efficiency, and asset longevity.
