Why get involved in IEC?

MET-CERTIFIED aims to accelerate the

adoption of insurable and bankable marine

energy technologies.

This is done by advancing internationally

recognised standards and certification

schemes (under IEC)

and by applying them in eight test and

verification cases.

What will we

learn through

Met -Certified? The insurers as an example: (since the banks demand insurance): Insurers need standards for: • Certification of technology • Resource assessment • Quality and construction assessment • Design assessment • Power curve measurements • Installation assessment • Operation assessment • Full load hours • Tests of at least 12 months or 8,000 running hours

In summary: • The certification of all aspects of a marine energy project • 3rd party verification recognized by the industry as credible

Met -Certified?

Standardization needs

STANDARDISATION NEEDS: • Consider real time and time domain software • Consider turbulence • Extend standards for scaling • Testing and certification on fish mortality • Develop a standard for installation • Wake/plants/arrays should be considered. • Design tools should be developed • Floating requirements should be developed. • Develop a standard on river resource assessment (done) • There is a need for power curve assessment & design • There is a need for procedures for manufacturing • OTEC needs specific standards (ongoing) • There is the need for specific classes for site characterisation • Umbilical’s and connectors need to be considered • Corrosion needs to be considered • There is a need for designs in all water scenarios • Guidelines and certification for marine operations • Standardised protocols on data collection and reporting

• 24.4 m long vessel designed

for road haulage and tug

boat installation

• 9.9 m diameter Tocardo T2

turbine

• 4 point taut mooring spread

• 100 kW grid power in 2 m∙s-

1 flows

TFS-demo

• Installed off the island of Texel in

2015

• T1 turbine testing initially, T2

installed 2016

• Rebranded as ‘TFS’ and installed

at EMEC berth 8 in March, 2017

• TFS retrieval planned for October,

before being replaced by the UFS

in 2018

TFS-demo

BlueTEC TFS

• Test results from Texel previously

reported on by NIOZ

• Submitted to ‘Renewable and

Sustainable Energy Reviews’ earlier this

year

• Further testing ongoing under MET-C

with EMEC ADCP drop

• Aim is to perform an external

assessment in accordance with IEC

62600-200

MET-Certified Tests - Performance

• Expected outcome 1 – comparison of seabed ADCP measurements (IEC

recommended) with turbine mounted measurements


Tocardo turbine mounted ADCPs

EMEC seabed ADCP


Seabed Mounted

• Profiles entirety of water column

• Capable of measuring waves

• Requires 2 ADCPs (upstream ebb and flood,

or adjacent)

• Achieving required upstream location not

always trivial

• Deployments usually remote and limited by

battery life

Turbine Mounted

• Profiles incoming rotor flow

• Does not require separate installation of

ADCP platform

• No capabilities for waves/ depth profile

• Platform motions need to be accounted

for

Pros

Cons

• Expected outcome 1 – comparison of seabed ADCP measurements (IEC recommended)

with turbine mounted measurements


• Expected outcome 2 – a recommendation to the IEC on how to address

rotor misalignment scenarios

• 62600-200 states: “the effects of flow misalignment on TEC performance

are not addressed in this TS at this time.”
