The ISC approachThe cornerstone of ISC´s competences derives from the ability to undertake the complete range of tasks associated with the development of complex mechanical installations and customiz-ing them to meet the client’s demands from the description of the task requirements to design, execution and completion of the special device or tool.

ISC assures that the job is carried out according to the time schedule, the technical specifications and within the budget.

We allocate a project manager and a project group with professional skill in the various en-gineering disciplines to perform the assignment which typically will include the following phases

ISC is equipped with the most modern and updat-ed computer calculation- and simulation software tools necessary for optimal solutions.

• Working with the client to identify the demand

• Conceptual design and cost estimate

• Detailed design and tender documents

• Tender and tender evaluation

• Contract management

• Inspection and quality assurance

• Commissioning and handover to client

• Maintenance and operation procedures

The CompanyISC Consulting Engineers A/S was founded in 1967 by Kjeld Thomsen M.Sc. (struct. Eng.) former as-sociate professor at the Technical University of Denmark.

Our 235 employees are located at our headquar-ters in Copenhagen and at our offices in Kalund-borg, Esbjerg, Kolding, Viborg and Aalborg.

ISC provides comprehensive independent consult-ing services within all fields of planning, feasibil-ity studies, civil, structural, mechanical, process, and electrical engineering on a worldwide basis.

ISC has special experience and knowledge in the field of planning and design of advanced civil works such as the “The Øresund Fixed Link” which connects Denmark and Sweden and with its 490m main span is the longest cable stayed railway bridge in the world. ISC also has special experi-ence in the design and planning of other civil works such as industrial plants, power stations, port facilities, oil & gas installations, wind farm installations, airports and railways. ISC has gained experience throughout the past more than 45 years on numerous projects carried out in more than 70 countries.

The staffThe combined staff of the company comprises 235 employees (2014) of which approximately 70 % are graduates in civil, structural, electrical or mechanical engineering and related disciplines.

The company´s expertise also covers manage-ment, planning, computer applications, informa-tion and maintenance systems, client consulting, site management and inspection.

Furthermore, ISC maintains standing agreements of cooperation with individual experts and public scientific institutions, thereby supplementing the company´s know-how in connection with as-signments requiring multi professional teams of specialists outside the company.

PILEGRIPPER

Mechanical tool for efficient monopile installation

The Pile GripperISC Consulting Engineers A/S has many years of experience in the design of complex offshore structures within oil and gas, drilling rigs and offshore wind. ISC´s experience in the design of offshore structures is founded on the knowledge obtained since 1975 in the offshore oil and gas industry.

Since ISC developed the world´s first pile grip-per for installation of monopiles in 2001, ISC has successfully undertaken many designs of advanced offshore structures involving multidisciplinary design of handling tools such as pile grippers and upending tools for the offshore installation of monopiles.

We offer our special know-how in the field of planning and design of offshore facilities and installations comprising jackets, topsides, founda-tions, bridges, Texas decks, cranes, piping, process, buoyancy systems, sea fastening and load out structures, mechanical notifications of drilling rigs, offshore surveys and site supervi-sions.

The pile gripper provides lateral support of mono-piles during driving, at a fixed vertical level. In the horizontal direction the pile gripper can move locally to adjust the monopile position, using two variable hydraulic systems. A third hydraulic sys-tem controls the opening and closing of the claw. Rollers in the claw ensure that the pile can move freely in the vertical direction.

ISC range of pilegrippers also comprises hull fixed low level types as well as innovative design of upending hinge tools used for installation of the very large monopiles. The upending hinge pro-vides safe lateral guidance during the lifting pro-cess on the vessel and ensures that the monopile is positioned correctly.

Ready for any challengeISC has a division of mechanical engineers, who in cooperation with our structural engineers have invented a number of innovative designs involving mechanical- as well as hydraulic solutions. We have for example for clients developed:• Ship loading and unloading equipment and gantry

cranes.• Hydraulic systems for large rotation bridges. • Rotating bearings for cranes. • Bearing for hydraulic activated systems for

rotating bridges.• Systems for unloading and mounting of heavy

structures. • Sea fastening systems for sea transportation.• Special offshore installations for the oil- and

gas sector.

There will always be a need for new innovative designs along with progress and ISC will always be ready to provide an innovative solution.
