博图斯·穆德的施罗德住宅修复理念
Rietveld Schröder House is one of the most representative work of the Dutch De Stijl movement. The house represents Mrs Schröder’s pursuit of a modern, open lifestyle. Moreover, it is also the first batch of restored modern architectural heritage, which is a milestone for Dutch and even worldwide architectural protection. Bertus Mulder is the leading architect responsible for the restoration. This article puts him in the context of the development of modern Dutch architectural protection theory and examines his guiding ideology, choices, results, and omissions, as well as the role of the Schröder family. Mulder focused on the restoration of the initial abstract space of the restored home, and this resulted in a drastic repair of the color and materials, as well as the removal of the household life history. A comprehensive reflection on his work will be helpful for future restoration of modernist architectural heritage.

Operators who want to im- or export bulk (coal, iron ore, scrap, etc.) by means of offshore bulk transshipment often want to determine the operability of their bulk transshipment configuration in an early stage to assess if offshore floating bulk transshipment is a feasible option for im- or export of the commodity. The downtime of such offshore (un)loading operations may be unacceptably large. The operational windows may become limited. This implies insufficient im- or export volumes, which may result in large and expensive storage capacity onshore.
In this paper a methodology is proposed to assess the operability of offshore floating bulk transshipment. Offshore bulk transshipment is a multi-phase operation. For offshore operations consisting of multiple phases, persistency of the environmental conditions has to be considered. Persistency analysis allows for multiple operational phases, individual phase duration and shift of sea states during the operation.
The proposed methodology shows that using persistency data of the waves (wind and current are not considered yet), the downtime of an offshore floating bulk transshipment operation can be estimated more accurately. Compared to persistency analysis, scatter analysis (using wave scatter diagrams) resulted in an optimistic estimate of the downtime. Persistency analysis is better in demonstrating the influence due to each consecutive step on the total operability. This methodology could be further extended to other multi-phase offshore operations. ...
