TECHNICAL ASSISTANCE

We offer consulting services in design, technical assistance, hydrodynamic, structural design, problem solving and more, for our partners and customers. Ranging from oil and gas companies, ship owners, fish farming to offshore wind.

TECHNICAL ASSISTANCE

Martin Linge STL

Challenge:

Conversion of tanker to FSO
Use of existing mating ring
Thickness measurements show reduced thickness
Higher loads than initially designed for
DNV GL contracted to evaluate existing design

Solution - Review, refine and update:

Load calculations and combinations
Load application
Rule requirements – design fatigue factors and acceptance criteria
Finite element modelling, element type, transition and eccentricities
Boundary conditions
Non-linear material behaviour and force redistribution

TECHNICAL ASSISTANCE

P80 Wind/Wave device

Task:

Review and update design basis for the platform

Modify design to optimize:

Heading stability in waves and current
Motion behaviour with respect to wind turbine performance
Global strength
Arrangement and stability
Mooring
Weight and cost
Constructability

TECHNICAL ASSISTANCE

We contribute to innovative fish-farm solutions

Cefront has assisted with hydrodynamic models and structural analysis for several fish farm concepts.

Spread or turret moored – disconnectable for service & maintenance.
Closed sides reduces exposure to Lepeophtheirus salmonis (salmon louse) and escape of fish.
Equipment for good working environment designed into the solutions, cranes, handling and accommodation quarters.

The Havfarm project:

Mooring Analysis in cooperation with Seasystems
Turret / mooring system design and analysis

The Aquatraz project:

Technical assistance
Structural design, hydrodynamic loads and responses
Model test specification and follow up
