Ampelmann idea

Ampelmann idea conceived in Berlin during an offshore wind conference in Berlin, the concept of the Ampelmann system was conceived. A flight simulator upside down, capable of compensating all six degrees of freedom of a vessel and making transferring offshore much safer. The code name Ampelmann was born to illustrate that the system should enable ‘Offshore access as easy as crossing the street’.

Conference in Berlin


University research

The first research thesis was started at the Delft University of Technology to look into the possibilities of such an inventive idea.


Ampelmann patent

After researching the subject a patent was filed on the Ampelmann system. The invention was presented at the European Wind Energy Conference in London.


Scale model tests

The next step in system development was to test the functionality of a scaled system. Dry tests were conducted by putting two hexapods (the assembly of two frames and six cylinders) on top of each other, in which the top hexapod could compensate the motions generated by the lower system.

The next step was a wet test: the scale model was mounted on a rowing boat in a tank facility at Civil Engineering in Delft where the compensating technology was put to the test and succeeded.


First prototype


Prototype phase

After successful scale tests, the start of the full-scale prototype started. An ambitious goal was set: design and construct a completely new system from scratch while getting it offshore proof, tested and certified. And do that within a year with 5 engineers!


The Demonstrator and the start of the company

The prototype, called the Demonstrator, was tested onshore and shown to the public in the home town Delft in the summer. Later that year the system was fully tested onshore and in the port.

At the end of the year the system reached its major goal: the first ever offshore transfers were made on the North Sea using an Ampelmann. The company was established to bring the new successful innovation to the market.

First commercial project with the A-type

Preparations were made for the first commercial job: supplying safe offshore transfers to the P-14A platform in the North Sea, which was decommissioned by the Smit Taklift 4. The first ever project was successfully concluded and plans were made to implement improvements in the next system. The construction of the A-02 was started by the end of the year.


Own production lot in the RDM in Rotterdam

The production facilities were housed in the RDM in Rotterdam Harbour. The new A-02 was launched during the year and the Demonstrator was upgraded and was named the A-01.

The prime minister of the Netherlands transfers used the system and Ampelmann received national news coverage. Multiple projects and offshore tests were done during the year. The workforce expanded to about 10 people.


Doubling the fleet

The company was growing rapidly. The A-03 and A-04 were added to the fleet and systems were operational around the world.


GXL, KIB, 100.000 transfers

Next to adding another four systems to the fleet, a number of innovations were added: an improved gangway was built with an extended length of 25 meters. A KIB system was launched to transfer cargo up to 100kg, reducing the need for a platform crane. With 100.000 safe transfers reached this year Walk to Work was becoming more and more a standard way of transferring people offshore.


Launch E-type

Following client demands, a larger system was constructed: the E-type is a scaled up version of the A-type. It has 3m stroke cylinders (instead of 2m) and is capable of working in higher sea states and compensating 100t on top of the system.

This was put to the test when the world’s first fully motion compensated crane (Cargo Transfer System) was tested offshore. Other activities were testing wirelining from a vessel instead of from a platform and developing a system to transfer LNG offshore, vessel to vessel.


Adding O-types to our fleet

The manufacturing of new Ampelmann systems is ramped up. To support further growth and international expension, Ampelmann recognized the need for a strong partner. IK Investment joined the company as the main shareholder. With their help, further expansion of the fleet was achieved by acquiring another Dutch offshore access specialist called Offshore Solutions.

Their fleet of O-types was incorporated with a very strong track record in providing a 24/7 connection to a platform. A smaller, electric system called the L-type was also being developed. This system can be installed on smaller vessels, aiming for the crew change market.


Launch O-type


Growing larger

Ampelmann is expanding around the globe, in order to be where the clients are. The first office abroad is opened in Singapore. After tests in 2012, the Cargo Transfer System is fully redesigned and successfully transfers 5t to an offshore platform in the Netherlands.

An improved L-type system (system for small crew vessels) is launched and tested in Brunei. The fact that motion compensation is key in increasing efficiency and safety is demonstrated by the motion compensated lifeboat exchange in the UK sector; a project called Atlas.




1 million transfers worldwide!

The demand for offshore access continues to grow both in offshore wind and the oil and gas sector. Safe offshore access is well accepted, which is demonstrated by one million transfers being reached in January. Later that year that was even doubled to two million.

Jim Craig takes over the helm of the company from Jan van der Tempel, both founder and inventor. Offices around the world are being opened in Brunei, Houston, Rio de Janeiro, Aberdeen and Doha. The new production facility is opened in Rotterdam, in the former navy submarine yard (Onderzeebootloods).

Improving the business

A fully winterized gangway is designed to work in the cold climate conditions of Sakhalin for SEIC. The system is build and tested by the end of this year. Further penetration of the cargo market is done with the E1000, a fully compensated gangway able to transfer people and hoist cargo up to 1 ton, making it the Swiss army knife for offshore maintenance campaigns. A promising L-type mark 4 is being conceived on the drawing board, making the system smaller, lighter and improved workability. Finally, a move to a new office location that matches the young and innovative spirit of the company.
