Reference excerpt

Heerema Marine Contractors (HMC) is a contractor headquartered in the Netherlands most notable for operation of three of the largest crane vessels in the offshore industry.

History Heerema Marine Contractors was formed in 1948 by Pieter Schelte Heerema as a small construction company providing oilfield platforms in Venezuela. In the 1960s the company focused on the North Sea offshore developments. The company developed crane vessels to lift large offshore platforms and modules. The ship shaped crane vessel Challenger was equipped to lift 800 t. The need for large stable crane vessels to operate in the North Sea environment lead the company to develop the first large semi-submersible crane vessels. In 1978, HMC commissioned Mitsui to construct the two sister semi-submersible crane vessels, DCV Balder and SSCV Hermod. These vessels could lift 5,400 tonnes with the twin cranes, and were later upgraded to 8,200 tonnes. In 1988 HMC formed a joint venture with McDermott called HeereMac.

The SSCV Thialf was added to the HeereMac fleet, and upon the split of the companies in December 1997, Heerema took ownership of the Thialf, the largest deep water construction vessel and is capable of a tandem lift of 14,200 t (15,600 short tons) The DCV Balder was affected by a flooding incident in 2006 and was put out of service for a few months.

Vessels Heerema presently owns and operates the following crane vessels:

DCV Balder DCV Aegir SSCV Thialf SSCV Hermod - Decommissioned late 2017 SSCV Sleipnir Kolga tug Bylgia tug Plus a number of barges.

Worked examples

Example 1 — a first encounter with Heerema Marine Contractors

Start with the simplest possible case. Write down what Heerema Marine Contractors claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Heerema Marine Contractors before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Heerema Marine Contractors ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Heerema Marine Contractors

In research: Heerema Marine Contractors appears in engineering research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Heerema Marine Contractors in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Heerema Marine Contractors is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1948 establishments in the Netherlands, Construction and civil engineering companies established in 1948, Engineering companies of the Netherlands, so understanding it makes those chapters shorter.
In everyday life: Look for Heerema Marine Contractors outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
