SIM-C Simulation

SIM-C is a powerful simulation tool developed by Caley Ocean Systems, giving users access to the expertise and know-how gained from over 50 years’ experience in offshore handling systems.

Combining powerful simulation technology with engineering insights gained from working on industry leading projects, SIM-C enables users to confidently evaluate the suitability of their offshore systems at the concept stage.

50 years of Innovation

Caley understands the challenges of working in a demanding offshore environment know about the sea, understand the marine environment and have been innovating handling solutions continuously for 50 years.

There is no substitute for experience

Having applied control techniques and motion compensation in one form or another on almost every project undertaken in recent years’, Caley has led the way with the development of new methodologies that permit desktop testing long before going to sea.

Caley’s SIM-C simulation package, developed in conjunction with industry leaders and customers encapsulating a broad range of industry experience, is the realisation of these benefits.

SIM-C brings together a suite of software tools and performance parameters that can be thoroughly developed, tested and demonstrated within the delivery time frame of a typical build programme.

Active Heave Compensation – Holistic Sensor Selection

The benefits of Active Heave Compensation are well known:

  • Increased operating window
  • Reduced dynamic loading
  • Accurate load handling

Caley is at the forefront of Active Heave Compensation systems, using its experience to take a holistic view to sensor selection so that all contribute appropriately to the overall trade-off between performance and cost, enabling:

  • Optimised control – with minimal latency in signals, non-linear compensation and advanced filtering to get the best possible performance between the MRU and the motion compensation achieved.
  • Advanced AHC – algorithms that make use of Kalman Filtering to predict motions or incorporate additional sensors all help to maximise compensation for very high performance applications. There is even the potential to include friction and deadband compensating terms again where needed.

Applications include:

  • Seabed soft landing
  • ROV Launch and recovery
  • Crane hook compensation
  • Well intervention.
