Source-derived summary

SSCV Hermod was a semi-submersible crane vessel operated by Heerema Marine Contractors.

History

Semi submersible crane vessel (SSCV) Hermod was constructed in 1979 by Mitsui Engineering & Shipbuilding Co., Ltd. Hermod and sister vessel, Balder were the world's first semi-submersible crane vessels. In the early 1980s these vessels set several lift records while operating in the North Sea.

Hermod was retired at the end of 2017. She was loaded on Dockwise Vanguard and taken to Dinghai District, Zhejiang province for scrapping at Zhoushan Changhong International Ship Recycling. 98% of the ship's materials will be reused.

Design

The hull consisted of two floaters with three columns each. The transit draught of 12 meters was normally ballasted down to 25 meters for lifting operations; at that load, the floaters (with a draught of 12 meters) were well-submerged, reducing the effect of waves and swell.

Propulsion was by two controllable pitch propellers and two forward, retractable, controllable pitch thrusters.

Editorial summary

Begin with the source’s own compact description: “Hermod (ship)” is semi-submersible crane vessel. The dossier treats that line as a proposition to test through Hermod, ship and semi-submersible, not as a finished interpretation.

Editorial reviewA practical starting point whose main value is the path it opens into stronger specialist and primary sources. The current lead gives the account dated anchors—1979, 2017—that can be checked directly. The selected authority fields contribute no independent date. For this dossier, Hermod, ship and semi-submersible is the immediate research focus.
Editorial analysis

Why this record matters

The phrase “semi-submersible crane vessel” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.

Evidence profile

The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Dec 14, 2025. The linked authority identifier is Q2207838. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1979 and 2017.

Critical limits

Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Use the entry as an orientation point, then follow its citations and revision history. Names, dates and institutional relationships should be checked against the original record.
